TEE TEST PROCEDURE FOR HYDRAULIC SYSTEM (CONT)
(Sheet 27 of 27)
LOCATION/ITEM
ACTION
REMARKS
NOTE
Find the leakage rates for the right and left
cylinders. Use the test information from System
Test, Pump Test and Blocked Cylinder Tests.
Example: Find the leakage rate for the lift
cylinders.
Test 24: flow rate of pump and control
valves.
Test 31: flow rate of pump, control valves,
and left side cylinder.
Test 4:
flow rate of pump, control valves,
and both cylinders.
The system components tested in Tests 24 and
81 are the same except for the left side cylin-
der. So the difference in flow rates must be the
leakage in the left side cylinder. Subtract the
test information for Test 31, from the test in-
formation for Test 24.
The system components tested in Tests 31 and
4 are the same except for the right side cylin-
der. So the difference in flow rates must be the
leakage in the right side cylinder. Subtract the
test information for Test 4 from the test infor-
mation for Test 31. Make a comparison of the
test values with the values on Chart C.
